The Energy Regulatory Commission (CRE) takes a crucial step in the integration of electric and plug-in hybrid vehicles into the National Electric System (SEN) by presenting the General Administrative Provisions (DACG).
These provisions, recently published in the National Commission for Regulatory Improvement (Conamer), aim to regulate the orderly and safe connection of charging infrastructure for electric and plug-in hybrid vehicles to the SEN.
One of the main innovations of this framework is the development of a digital platform to track the evolution of the charging infrastructure.
To achieve this, three guidelines were established: General requirements for those interested in integrating the charging infrastructure, promotion of the involvement of qualified personnel in the installation and connection of equipment, and information that end-users and administrators must provide to access the public information platform.
In this way, the groundwork is laid for end-users to potentially become prosumers, gaining control over their demand.
Furthermore, with a Smart Grid in place, they can have greater interaction with the distributor and the National Energy Control Center.
The document also proposes a reference framework to determine if the end-user is acquiring energy at a fair price, based on international best practices in the market.
New parameters for charging infrastructure:
Regarding the request for electricity supply service and connection of Charging Infrastructure, two options are detailed based on electrical voltage.
End-users wishing to install charging infrastructure in the same property or condominium already receiving Basic Supply service at Low Voltage or Medium Voltage must request a new electricity supply service contract independently of the one they currently receive.
On the other hand, those wishing to connect infrastructure to a voltage equal to or greater than 69 kV must submit their connection request to CENACE.
For voltages lower than 69 kV, connection requests will be handled by the distributor.
Regarding installations and risk signaling, the procedure and type of protection to be followed when installing an intelligent electric charger according to charging modes are determined.
Chargers with Mode 2 charging intended to be wall-mounted but user detachable, or used in a shock-resistant casing, will use protection equipment as required by the corresponding NOM or IEC 62752 standard.
Those equipped with Mode 3 charging must provide a protective grounding conductor to the EV or PHEV socket and/or connector. Mode 4 chargers can be permanently connected or connected via cable and plug to the power supply network.
It is highlighted that electric chargers installed in charging stations must have at least fast or ultra-fast charging mode to allow users to charge their vehicles quickly.
Charging stations must have charging infrastructure compatible with at least two types of connectors available in the national territory.
Public charging stations must display information on compatible connector types, charger type, charging mode, usage instructions, and, if possible, estimated charging time.
Electricity prices for charging must be visible and published on boards in pesos per kWh ($/kWh) and must match the prices reported to the Energy Regulatory Commission, in accordance with applicable legal provisions.
Regarding surveillance and control of the infrastructure, the Commission may request information from end-users when necessary to review or verify installation conditions. The same applies to distributors and administrators.
